\ WHEEL-LOCK.

Specification of Letters Patent.

Patented April '21, 1908.

Application filed April 29, 1907. Serial 'No. 371,014.

.pense with the use of nuts for securing the wheel on the aXletree.Second,rto provide :a means whereby the Wheel may be readily secured toor removed :from the axletree without the necessity of first removingthe sand guard from the hub of the wheel. Third, to provide a meanswhereby the wheel may be readily secured to or removed from theaXletree, and at the same time to so secure the wheel that there will beno danger of its becoming accidentally disconnected therefrom, and,fourth, to so secure the wheel to the axletree that a sand guard will beprovided at both ends of the wheel hub. I-attain these objects by themechanism illus trated in the accompanying drawing in which Figure 1 isa vertical section of the hub on the line as as of Fig. 5, and theaXletree in place with my securing appliance engaging it. Fig. 2 is thesame showing a modified .form of securing appliance having a hinged orpivoted joint near one end. Fig. 3 is the same showing a straight solidarm upon the securing device. Fig. 4 shows a short arm upon the securingdevice, secured in place by means of a screw placed laterally into thehub and through the end of the arm, and

Fig. 5 is an elevation of the reverse side of the sand guard andactuating collar at the inner end of the hub, and of the securing armsand the axletree cut ofi approximately upon the line y y of Fig. 1.

Similar letters refer to similar throughout the several views. 1

A represents the wheel hub, B a portion of a spoke and O is the aXletreewhich has a groove 0 around it at the inner end of the wheel hub. Myappliance consists, first, of a latch D, of any convenient or availableform and having a lip D projecting at right angles therewith in positionto be made to engage the groove 0 in the axletree, as indicated in Figs.1 and 2, in such a manner that while the wheel may revolve freely uponthe parts aX-letree it will be held securely against endwise motion. inits normal position this arm is held out of contact with the groove .cby means of the spring d, and to throw and hold it in contact with theaXletree in said groove I plate a metallic ferrule G around the end ofthe hub A and over this 'I place a sand guard F which has curvedbearings integral with its end surface in position so that if the guardis in the position indicated in Fig. 1 they will engage the backs of thelips D and force them down into the groove 0, as indicated, but if theguard is turned around, as indicated in Fig. 5 the spring (I will throwthe arm D back so that the lip D will be drawn entirely out of thegroove 0 and the hub may be readily removed from the axletree C.

The latch D may be made with a long integral arm, as indicated in Figs.1 and 3, terminating with a nut (1 arranged to hold it to place so thatthe lip D will properly engage the aXletree in the groove 0, or it maybe made with a pivotal joint, as at ein Fig. 2,

in which case the portion having the nut (1 upon it is immovable in thehub, the entire motion of the arm being in the portion having the lip Dupon it, and in some instances 1 have used .a short arm, as indicated inFig. 4, placed in a short mortise in the end of the hub A and secured inplace by means of a "screw 6 passing into the :hub and through a hole inthe end of the arm D, as indicated. I mention these several forms asindicating the diversity of forms that may be used,'in dicating that itis, not the special form of latch, but the manner of applying it, thatenters into the necessary elements of my invention.

Where the nut d is used to-secure the arm of the latch D it is necessaryto rovide some means of looking it in place so t at it cannot become,accidentally, removed from the arm, and for this purpose it may beplaced close enough to the rim of the sand guard F so that it cannotturn, as indicated in Fig. 2, or any available form of nut lock may beused, as indicated by the late d in Fig. 3.

It will be noticed, see igs. 1 and 2, that the aXletree 0, passes fromthe right through the hub, and. extends to a oint, where its end is justflush with the left and end of the .hub A so that the sand guard F maybe closed and secure dust guard at this end of the hub. At the other endof the hub I securely attach a ferrule G around the end of the hub andplace the sand guard F over it with the end of the guard projectinginward far enough to form a close joint around the flange c of theaXletree O, thus forming a practical sand guard at this end of the hub.

To utilize the guard F for manipulating the latches D D it must be madeeasily revoluble upon the ferrule G and, at the same time, it must be soarranged that it will not slip off the ferrule endwise, or become looseand turn thereon except by the direct act of the operator, and for thispurpose it may be securely clamped to the ferrule by means of thumbscrews, as g, or by any other of the well known mechanical appliancesavailable for the purpose, and should be provided with a slot, as g, orsome other available appliance to allow it to be revolved a shortdistance, as shown in Fig. 4 and indicated by the arrow in Fig. 5, itbeing understood that the thumb screw or thumb piece 9 may indicate thehead of a screw designed to be screwed into the ferrule G or it mayindicate a thumb piece on a spring catch arranged to operate in the slotg and act upon the surface of the ferrule G, or as the manipulatingelement of any other available locking device for the guard F.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent of the United States, is 2 1. In combinationwith a wheel hub, and an aXletree having an annular groove around itnear the inner end of the hub, latches secured in the hub in position toengage the groove in the aXletree, a ferrule aroundone end of the hub, asand guard revolubly mounted over said ferrule, bearings inside saidsand guard in osition to be made to actuate the latches w en the sandguard is revolved, and means for locking the sand guard. in place on theferrule.

2. In combination with a wheel hub, and an aXletree having an annulargroove in it near the end of the hub, latches secured in the hub, aferrule around the end of the hub, a sand guard revolubly mounted on theferrule, bearings in the sand guard in position to actuate the latchesin one direction when the sand guard is revolved, means for locking thesand guard firmly in place, and springs on the latches for actuatingthem one way.

3. In combination with a wheel hub, and an aXletree having an annulargroove near the inner end of the hub, latches secured in the hub inposition to engage the groove in the aXletree, nuts securing saidlatches in place, at one end. of the hub, and nut locks to prevent saidnuts from turning off of the ends of the latches; a ferrule securedaround the other end of the hub, a sand guard revolubly secured aroundthe ferrule, bearings in the sand guard in position to actuate thelatches to force them into the groove in the axletree, means for lockingthe sand guard securely to the ferrule, and springs for forcing thelatches out of the groove in the axletree.

4. In combination with a wheel hub, and an axletree having an annulargroove in its surface, an arm passing longitudinally through the hub, anut securing said arm in place, a latch 1pivoted to one end of said arm1n position to e made to enter the groove 1n the axletree, and means forforcing said latch into or out of said groove, substantially as and forthe purpose set forth.
